Relatives of Japanese abducted by North Korea said they were upset by remarks by Kurt Campbell, the top U.S. diplomat on East Asian affairs, in their meeting Monday at which he urged Japan to address the issue of parental child abductions.

Campbell devoted nearly half of his time at the meeting at the State Department to stressing the importance of the parental child abduction issue, according to Teruaki Masumoto, whose sister, Rumiko, was abducted by North Korean agents.

The United States and other countries are currently pressing Tokyo to sign an international treaty on dealing with cases of parental child abductions.
